A review of the effect of hydrothermal aging on the mechanical properties of 2D fiber‐reinforced resin matrix composites

Abstract

Abstract2D fiber reinforced resin matrix composites (2D FRRMC) are widely applied for aerospace, generator blades, and other high‐end equipment manufacturing fields due to their excellent mechanical properties. However, 2D FRRMC will face a variety of complex environments in the service process, and the long‐term complex environment will significantly impact the physical and mechanical properties of 2D FRRMC. It is necessary to understand and analyze the changes of materials during service. A comprehensive review of the research on the effect of hydrothermal aging on the mechanical properties and re‐ drying of 2D FRRMC in recent years was presented in this article, which contains interlaminar shear properties, compression properties, tensile properties, and aging mechanism, etc. Finally, the current challenges and prospects of 2D FRRMC were discussed. These discussions and proposed strategies will enlighten thoughts and offer ways to apply 2D FRRMC in complex environments better, study 2D FRRMC in complex environments, and study the effects of hydrothermal aging on materials in the future.

The influence of hygrothermal aging on the hoop tensile strength of glass fiber wound polymer composites fabricated via filament winding technique

“…In harsh environments, the mechanical properties of FRP composites deteriorate as the working temperature rises between 70-80 °C. The aging period, chemical treatment (such as exposure to the sea and distilled water), and working temperature have all been shown to influence the overall strength of FRP composites [38][39][40][41][42]. Recent research has shown that moisture influences matrix osmotic cracking due to the expansion of the gap between fiber and matrix, as well as the debonding of fiber and matrix.…”
